Restrict Portal Users from go to Now platform.

[rohanbhatia]

Hi,

We want to restrict Our portal Users (CSM portal) to go to Now Platform. 
We have a UI script and modified spEntryPage as well.
UI script currently works well when someone removed  "/csm" and spEntryPage redirects users to the right portal.
Problem is when someone copy pasted url like "now/nav/ui" or "now/sow/home" they get access of now platform.
We want to restrict it and redirect them again to CSM Portal.

Ui type = desktop
Global = true

Application scope = Global
